Terbium Metal is the important additive for NdFeB permanent magnets to raise the Curie temperature and improve temperature coefficiency. Another most promising use of distilled Terbium Metal, is in the magnetostrictive alloy. There are also other applications for some special master alloys. Terbium is reasonably stable in air. It is a silvery-grey metal, and is malleable, ductile, and soft enough to be cut with a knife. It is a rare earth metal found in cerite, gadolinite and monazite. The element itself was isolated only recently.
